Background To investigate the relationship 25-hydroxy vitamin D (25OHD) level among children and in children with type 1 diabetes mellitus (T1DM). Methods A case–control study was conducted to compare the serum 25OHD levels between cases and controls. This study recruited 296 T1DM children (106 newly diagnosed T1DM patients and 190 established T1DM patients), and 295 age- and gender-matched healthy subjects as controls. Results The mean serum 25OHD in T1DM children was 48.69 ± 15.26 nmol/L and in the controls was 57.93 ± 19.03 nmol/L. The mean serum 25OHD in T1DM children was lower than that of controls (P < 0.01). The mean serum 25OHD level (50.42 ± 14.74 nmol/L) in the newly diagnosed T1DM children was higher than that (47.70 ± 15.50 nmol/L) in the established T1DM children but the difference was not statistically significant (P = 0.16). HbA1c values were associated with 25OHD levels in established T1DM children (r = 0.264, P < 0.01), and there was no association between 25OHD and HbA1c in newly diagnosed T1DM children (r = 0.164; P > 0.05). Conclusion Vitamin D deficiency is common in T1DM children, and it should be worthy of attention on the lack of vitamin D in established T1DM children.

Vitamin D Levels

In this prospective controlled study, we examined 25 adults with adequately controlled (HbA1c level < 8.0%) type 1 diabetes mellitus (T1DM) and 49 conditionally healthy adults, intending to reveal the diversity of vitamin D metabolism in the setting of cholecalciferol intake at a therapeutic dose. All patients received a single dose (150,000 IU) of cholecalciferol aqueous solution orally. Laboratory assessments including serum vitamin D metabolites (25(OH)D3, 25(OH)D2, 1,25(OH)2D3, 3-epi-25(OH)D3 and 24,25(OH)2D3), free 25(OH)D, vitamin D-binding protein (DBP) and parathyroid hormone (PTH) as well as serum and urine biochemical parameters were performed before the intake and on Days 1, 3 and 7 after the administration. The studied groups had no significant differences in baseline parameters except that the patients with diabetes showed higher baseline levels of free 25(OH)D (p < 0.05). They also lacked a correlation between the measured and calculated free 25(OH)D in contrast to the patients from the control group (r = 0.41, p > 0.05 vs. r = 0.88, p < 0.05), possibly due to the glycosylation of binding proteins, which affects the affinity constant for 25(OH)D. The elevation of vitamin D levels after the administration of cholecalciferol was comparable in both groups, with slightly higher 25(OH)D3 levels observed in the diabetes group throughout the study since Day 1 (p < 0.05). Overall, our data indicate that in patients with adequately controlled T1DM 25(OH)D3 levels and the therapeutic response to cholecalciferol is similar to that in healthy individuals.

Vitamin D Levels

Background: Previous research state the correlation between vitamin D deficiency and Type 1 diabetes. The deficiency of Vitamin D is caused by vitamin D intake, sunlight exposure, or nutritional status. Indonesia, as a tropical country, is close to the equator and receives sunlight all year long. Little research has been done on vitamin D levels in children and adolescents with Type 1 Diabetes in Indonesia.Objective: The study aims to determine the relationship among sunlight exposure, nutritional status, food intake, and vitamin D levels in children and adolescents with Type 1 Diabetes.Methods: The study design was cross-sectional with a sample size of 31 children and adolescents aged 5-19 years. Sunlight exposure data were collected using the Sun Exposure Questionnaire form, nutritional status o BMI/age data were using the WHO Anthro, food intake data were using the Semi-Quantitative Food Frequency Questioner, and vitamin D level data were using the ELISA method. Statistical analysis was conducted by using SPSS Version 21 with Pearson and Spearman correlation test.Results: All respondents showed vitamin D deficiency. Most respondents had low sunlight exposure and nutritional status in the normoweight category. The majority of respondents had good energy and protein intake, excess fat, low carbohydrates, and low vitamin D and calcium.Conclusion:There is a positive relationship between sunlight exposure and vitamin D level (p = 0.001, r = 0.627). However, there is no relationship among nutritional status, protein intake, fat, carbohydrates, vitamin D and calcium on the level of vitamin D (p = 0.409; p = 0.240; p = 0.311; p = 0.822; p = 0.231; 0.382).

Abstract Objective There is an increased level of low-density lipoprotein cholesterol (LDL-C)in children with type 1 diabetes mellitus(T1DM). In addition, the Vitamin D level in T1DM patients is usually below the normal reference range. The aim of this study was to explore the relationship between Vitamin D levels and LDL-C in Chinese children with T1DM. Methods A retrospective cross-sectional study was conducted in the Endocrine inpatient wards of Tianjin Children’s Hospital, 143 children with T1DM were included. The related clinical and laboratory examinations, including anthropometric parameters, lipid profiles, and Vitamin D levels, were collected in all subjects. Results The univariate analysis results did not show a significant correlation between Vitamin D levels and LDL-C (P=0.634). Furthermore, a nonlinear relationship was observed between Vitamin D levels and LDL-C by smooth curve fitting after adjusting for potential confounders. A multivariate piecewise linear regression model revealed a significant negative association between LDL-C and Vitamin D levels when LDL-C was greater than 3.1 mmol/L(β -2.9, 95% CI -5.4,-0.5; P=0.022). However, we did not observe a significant relationship between LDL-C and Vitamin D levels when LDL-C was lower than 3.1 mmol/L(β 2.4, 95% CI -0.2,5.1; P=0.076).Conclusions This study identified a nonlinear relationship between Vitamin D levels and LDL-C independent of other potential confounding factors, suggesting that the deficiency or insufficiency of Vitamin D in T1DM children with high LDL-C levels should be considered, especially LDL-C is higher than 3.1 mmol/L, which provides evidence of the timing about Vitamin D supplementation in T1DM children.

Background/Aims: In adults, lower vitamin D has been associated with increased albuminuria. This association has not been extensively studied in youth with or without type 1 diabetes. Methods: We examined the cross-sectional association between vitamin D and albuminuria (urine albumin to creatinine ratio ≥30 mg/g) in 8,789 participants of the National Health and Nutrition Survey 2001–2006 (NHANES), who were 6–19 years old. Further, we examined the association between vitamin D and albuminuria in 938 participants from the SEARCH Nutritional Ancillary Study (SNAS), a longitudinal cohort of youth with type 1 diabetes. Results: Of the NHANES participants, 5.3, 19.5, and 53.7% had vitamin D levels <30, 50 and 80 nmol/L, respectively. Albuminuria was present in 12.8% and was more common in younger children, females, non-Hispanic whites, non-obese children, and children with hypertension. After adjustments, there was no association between vitamin D and albuminuria. Among the SNAS participants with type 1 diabetes, we also found no association between baseline vitamin D and subsequent albuminuria in unadjusted or adjusted analyses. Conclusion: We did not find an association between serum vitamin D and albuminuria in either non-diabetic youth or those with type 1 diabetes. Further research is needed to more fully understand this relationship.

Background Higher 25(OH)D3 levels are associated with lower HbA1c, but there are limited UK interventional trials assessing the effect of cholecalciferol on HbA1c. Aims (1) To assess the baseline 25(OH)D3 status in a Manchester cohort of children with type 1 diabetes (T1D). (2) To determine the effect of cholecalciferol administration on HbA1c. Methods Children with T1D attending routine clinic appointments over three months in late winter/early spring had blood samples taken with consent. Participants with a 25(OH)D3 level <50 nmol/L were treated with a one-off cholecalciferol dose of 100,000 (2–10 years) or 160,000 (>10 years) units. HbA1c levels before and after treatment were recorded. Results Vitamin D levels were obtained from 51 children. 35 were Caucasian, 11 South Asian and 5 from other ethnic groups. 42 were vitamin D deficient, but 2 were excluded from the analysis. All South Asian children were vitamin D deficient, with mean 25(OH)D3 of 28 nmol/L. In Caucasians, there was a negative relationship between baseline 25(OH)D3 level and HbA1c (r = −0.484, P < 0.01). In treated participants, there was no significant difference in mean HbA1c at 3 months (t = 1.010, P = 0.328) or at 1 year (t = −1.173, P = 0.248) before and after treatment. One-way ANCOVA, controlling for age, gender, ethnicity, BMI and diabetes duration showed no difference in Δ HbA1c level. Conclusion We report important findings at baseline, but in children treated with a stat dose of cholecalciferol, there was no effect on HbA1c. Further studies with larger sample sizes and using maintenance therapy are required.
